  • a minimally invasive endoscopic approach to chronic isolated frontal sinusitis
    Operative Techniques in Otolaryngology-head and Neck Surgery, 2006
    Co-Authors: Roee Landsberg, Michael Friedman
    Abstract:

    Chronic isolated frontal sinusitis occurs infrequently. When it does, most of the Ethmoid cells are well aerated, and the frontal sinus is involved secondary to anatomic obstruction or inflammatory changes confined to the frontal recess. In this article, we describe a targeted endoscopic approach in which standard anterior Ethmoidectomy is unnecessary in treating this condition. Complete uncinectomy with resection of the terminal recess, or the agger nasi or frontal cell is followed by frontal sinusotomy. The Ethmoid Bulla and the maxillary ostium are left intact. The Ethmoid Bulla and the anterior wall of the supraBullar recess serve as an effective posterior boundary of frontal recess dissection in the coronal plane, and as a barrier between the surgical instruments and the anterior Ethmoid artery. The described technique may be insufficient in certain anatomic variations, such as frontal recess pneumatization originating behind the plane of the Bulla lamella. In these situations, the Ethmoid Bulla will need to be resected. It is concluded that chronic isolated frontal sinusitis can be effectively treated in select cases with a minimally invasive endoscopic procedure that is limited to the reestablishment of frontal sinus outflow.

    Co-Authors: Roee Landsberg, Yoram Segev, Michael Friedman, Dan M Fliss, Ari Derowe
    Abstract:

    Objective Chronic isolated frontal sinusitis occurs infrequently. In this condition, most of the Ethmoid cells are well aerated and the frontal sinus is involved secondary to anatomical obstruction or inflammatory changes confined to the frontal recess. The purpose of this study was to evaluate a targeted endoscopic technique where standard anterior Ethmoidectomy is unnecessary in the treatment of chronic isolated frontal sinusitis. Study design and setting This retrospective study was conducted in a large university-affiliated hospital and included 11 patients with chronic isolated frontal sinusitis who underwent endoscopic sinus surgery limited to the frontal sinus outflow. The Ethmoid Bulla was untouched in all cases. Follow-up continued for 19 to 40 months (mean 28.6 months). Results Frontal sinus outflow patency was verified in 9 patients (81.8%). Nine patients, including one with an apparent nonpatent frontal ostium, reported improvement. Two patients—one of whom had a patent frontal ostium—reported no improvement. There were no complications. Conclusion Chronic isolated frontal sinusitis can be effectively treated in selected cases by a targeted endoscopic procedure, limited to reestablishment of frontal sinus outflow. EBM rating: C-4

  • an endoscopic cadaveric study accessory maxillary ostia endoskopik kadavra calismasi aksesuar maksiller ostium
    2014
    Co-Authors: Alper Sindel, Murat Turhan, Eren Ogut, Mehmet Akdag, Muzaffer Sindel
    Abstract:

    Objective: Endoscopy is now being used for diagnosis and surgical treatment of disorders of the nose and paranasal sinuses. Direct observations of mucociliary clearance patterns have shown that there are clear cut pathways in the sinuses, with secretions always trying to leave through the natural ostia.’ Maxillar ostia is exists behind the upper part of the medial wall and often at intersection region of the rear lower infindubulum and lower front sur face of the Ethmoid Bulla. Accessory ostium exists at the 25-30% of the general population instead of the natural ostium. There are some features that differentiate the accessory ostium and natural ostium. Methods: To determine the incidence and location of the accessory ostium 29 fromaldehyde fixed adult cadaver was examined with endoscope. Results: The accessory ostium is encountered at 8 cases (13.8%). These are located at rare-middle, front-middle and rear in 2 (0.03%), 3 (0.05%), 3 (0.05%) cases respectively. Recognition of the maxillary ostia is tedious while performing endoscopic procedures which accounts for a high rate of orbital complications for a novice performing surgery in this region. Conclusion: It is therefore imperative to know the landmarks in this regions which may be obliterated by disease. Radiologist should be aware of this entity as it can appear as communication between the maxillary sinus and nasal cavity on sinus imaging examinations.
